Thank God I found you. You sir are a hero. You should teach at a University instead of all the professors who pretend to teach, those who go on an on for an hour complicating things and making life harder.
Brian Swarthout Just one question sir: at 4:15 you say that di is between C and 2f but how can that be possible? since f = (1/2)*C ==> 2f = C, right? so you're basically saying "di is between C and C." Is this right, or am I missing something? Thank you
Al Infinity Yes, you are right, it should say di between C and f. Sorry about that, thanks for catching my error and thanks for pointing it out to me…..that must be a copy and paste error from the convex lenses where it would say the image is between f and 2f when the object is beyond 2f. Again thank you, I will add a note to the video right now.
It has been 10 years since this video is posted and I am here to tell that you helped people a lot and that includes me as well! you are a lifesaver thank you!
Simply no other explanation is as clear as this one. I looked in my textbook, I looked at my teacher's notes, I looked at a few other videos, etc., but nothing compares to this one. Thank you so so so much for this video, you are absolutely amazing. I am on my way to watch a few more of your videos to clear up my understanding, and I also just subscribed! I will definitely recommend this channel to my friends. You have a gift for teaching; please don't stop! Thank you~
I've been looking for a decent resource on this for days and this is the first time I've actually seen the effects compared based on the position of the image. I cannot thank you enough, I wish that one day an $80 text book would be half as good as your explanations.
Immediately clear and effective explanation! I watched some other videos on the same concept and was still confused, but this was the exception for me. Also, I appreciate the length. Some videos are ~15-20min, which can take a lot of time. Thanks for the help!
hapamateo thank you for the very nice comment, yes I try to keep them all under 10 minutes. I try to get right to the point no sense going on about nothing just to hear yourself talk.
Goodness gosh! I really didn't knew that the way how the convex lens and concave mirrors form the images in the same manner till now! Thank you so much and that was so helpful rather than studying 10 different ray diagrams!!
this helped alot!! I have tests day after tomorrow and I was very worried as this concept was really confusing to me and honestly saying that my teacher made it so complicated!! thanks a lot once again. I'm gonna rock my test 😃😃
thank u for explaining this to me like a toddler. u taught me everything i need to know for my exam in 12 minutes that my teacher failed to teach me in 2 weeks. very helpful!
thank you so much!! i've been banging my head against a wall trying to understand the logic behind ray diagrams. this is the best explanation on youtube
the principle axis is the line that runs down the center of the lens or mirror. The focal point and center of curvature are located on the principle axis.
your teaching is excellent ... this the first time I watch your video all I can say .....it's very simple an easy to understand much better than my teacher who has complicated things keep up hero
I was falling behind in Physics for a couple of months and then I found your channel and I honestly couldn't be more thankful. This is one of the most helpful videos on here, and I'm doing good in physics altogether. Thanks a lot!
Love this video! Just wanted to point out though that in scenario 1 (do>C), you mentioned that di is between C & 2f. However, in the diagram you have it between C & f (and also you mentioned that C=2f) so I think that was a typo!

Thank you sir for your teachings as only because of you I could understand these diagrams. I could score good only because you made it simple for me to remember, many tried but failed and in the end it was you who could tell in such a easier manner. Sir because of you and these diagrams I could score more than I could except. Thank you so much.

Thank you so much, this helps a lot, I now know very much about concave and convex. I'm a junior in high school taking honors physics, this is great. I don't understand it much when I'm in school but you made me understand it in 10 minutes! Once again thank you
